Tls-crypt v2 is more complicated to implement a proper stateless
handshake. To allow state handshake this commit does
- introduce a new packet CONTROL_WKC_V1 that repeats the wrapped
client key.
- introduce a way to negotiate the support for this packet in the
three way handshake
Details about the protocol changes are in tls-crypt-v2.txt. Optional
arguments to the tls-crypt-v2 option have been added to explicitly
allow or disallow client that do not support the stateless handshake.

This is a preliminary description of tls-crypt-v2. It should give a good
impression about the reasoning and design behind tls-crypt-v2, but might
need some polishing and updating.
